Answer:

C x >=0

Step-by-step explanation:

Each term has to be defined

sqrt(5x) >= 0

Square each side

5x >=0

Divide by 5

5x/5 >=0/5

x >=0

sqrt(x+4) >=0

Square each side

x+4 >0=

Subtract 4 from each side

x+4-4 >=0-4

x >=0-4

The first is more restrictive so we use that

x>=0

Answer:

$y=\frac{5}{2}x-14$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)
Parallel lines always have the same slope

1) Determine the slope (m)

$y=\frac{5}{2}x-10$

In the given equation, $\frac{5}{2}$ is in the place of m, making it the slope. Because parallel lines have the same slope, the line we're currently solving for therefore has a slope of $\frac{5}{2}$ . Plug this into $y=mx+b$ :
